Abstract: An ultraviolet light fluid treatment device for irradiating a fluid flowing in a flow path tube with ultraviolet light includes a substrate; a light source disposed on the substrate and configured to emit the ultraviolet light; a light transmissive member disposed between the light source and the flow path tube and configured to transmit the ultraviolet light from the light source; and a support member fixed to the substrate and configured to hold an adsorption member that includes an adsorbent material adsorbing moisture. The support member has a reflective surface. The reflective surface is positioned between the light source and the adsorption member, and is configured to reflect the ultraviolet light from the light source.

Abstract: A light-emitting device comprising: a base member; a plurality of first light-emitting elements disposed on the base member; a plurality of second light-emitting elements disposed on the base member; a plurality of first wavelength conversion members; and a second wavelength conversion member. The first wavelength conversion members are respectively disposed on or above the first light-emitting elements. The first wavelength conversion members each comprises a light-transmissive body mainly containing an inorganic material, and a first phosphor layer on the lower surface of the light-transmissive body. The second wavelength conversion member is disposed on the base member to cover the second light-emitting elements and the first wavelength conversion members. The second wavelength conversion member comprises an encapsulating resin and second phosphor.
